移动脚手架技术的发展趋势

2018-11-09 20:56:28 常州亿创能源科技有限公司 阅读

移动脚手架在中国广泛使用,已经得到使用者的广泛喜爱和好评,我国在60年代初开始应用扣件式移动脚手架,由于这种脚手架具有装拆灵活、搬运方便、通用性强、价格便宜等特点,所以在我国应用十分广泛,其使用量已经占60%以上,是当前使用量最多的一种移动脚手架。但是这种移动脚手架脚手架的最大弱点是安全性较差,施工工效低、材料消耗量大,消费的生产成本比较高。

Mobile scaffolding is widely used in China and has been widely loved and praised by users. Fastener-type mobile scaffolding has been applied in China since the early 1960s. Because of its flexible assembly and disassembly, convenient handling, strong versatility and low price, it has been widely used in China and its usage has taken up a large proportion. Over 60% is the most mobile scaffold currently used. But the biggest weakness of this kind of mobile scaffolding scaffolding is its poor safety, low construction efficiency, high consumption of materials and high production cost.

移动脚手架的生产原料钢管在全国范围内普遍存在,钢管的产品比较大,全国移动脚手架钢管约有1000万吨以上,但是其中劣质的、超期使用的和不合格的钢管占80%以上,扣件总量约有10~12亿个,其中90%左右为不合格品,如此量大面广的不合格钢管和扣件,已成为建筑施工的安全隐患。据不完全资料显示,自2001年至2007年,已发生扣件式移动脚手架倒塌事故已经达到70多起,其中死亡200余人,受伤400余人。一起起的倒塌事故一直在提醒移动移动脚手架的生产厂家需要注意移动门式脚手架的质量,生产的产品要符合国家的生产标准,达到国家的产品执行标准。上世纪我国先后从国外引进门式脚手架、碗扣式门式脚手架等多种形式移动梯形脚手架。这几种移动梯形脚手架在中国广泛使用,已经普及到各大建筑公司,在建筑行业中广泛使用,并在不断的完善和健全,功能不断完善。

The raw material steel pipes for mobile scaffolding are ubiquitous throughout the country. The products of steel pipes are relatively large. There are about 10 million tons of steel pipes for mobile scaffolding nationwide. However, more than 80% of them are inferior, overdue and unqualified. The total number of fasteners is about 1.0-1.2 billion, of which 90% are unqualified products. Unqualified steel pipes and fasteners with large size have become potential safety hazards in building construction. According to incomplete data, from 2001 to 2007, more than 70 accidents of fastener-type scaffolding collapsed, including more than 200 deaths and 400 injuries. A collapse accident has been reminding manufacturers of mobile scaffolding that they need to pay attention to the quality of mobile scaffolding. The products produced should meet the national production standards and meet the national product implementation standards. In the last century, China imported portal scaffolding, bowl-button scaffolding and other forms of mobile scaffolding from abroad. These kinds of mobile scaffolding are widely used in China, and have been popularized to major construction companies. They are widely used in the construction industry, and are constantly improving and perfecting their functions.

门式移动脚手架在国内许多工程中也曾大量应用过,取得较好的效果,由于门式脚手架的产品质量问题,这种脚手架没有得到大量推广应用。现在国内又出现了一批门式脚手架生产厂家,其产品大部分是按外商的图纸进行钣金加工。碗扣式脚手架是新型脚手架中,推广应用最多的一种脚手架,但使用面还不广,只有部分地区和部分工程中大量应用。最近,国内一些移动脚手架企业引进国外先进技术,开发了多种新型脚手架,如插销式脚手架,CRAB模块脚手架、圆盘式脚手架、方塔式脚手架,以及各种类型的爬架。从技术上来讲,我国脚手架企业已具备钣金加工生产各种新型脚手架的能力。但是国内市场还没有形成,施工企业对新型脚手架的认识还不足。采用新技术的能力还不够,国内脚手架企业主要任务是对外加工。,没有形成一种比较稳定的市场,对移动脚手架的发展史不利的。

Portal mobile scaffolding has been widely used in many domestic projects, and achieved good results. Because of the quality problems of the products of portal scaffolding, this kind of scaffolding has not been widely applied. Now there are a number of domestic door scaffolding manufacturers, most of their products are processed according to foreign drawings. Bowl-buckle scaffolding is a new type of scaffolding, which is widely used, but it is not widely used, only in some areas and some projects. Recently, some domestic mobile scaffolding enterprises have introduced foreign advanced technology and developed a variety of new scaffolding, such as plug-in scaffolding, CRAB module scaffolding, disc scaffolding, square tower scaffolding, and various types of climbing scaffolding. Technically speaking, scaffolding enterprises in China already have the ability to process and produce various new scaffolds. However, the domestic market has not yet formed, and the understanding of the new scaffolding by construction enterprises is still insufficient. The ability to adopt new technologies is not enough. The main task of domestic scaffolding enterprises is external processing. A stable market is not formed, which is unfavorable to the development history of mobile scaffolds.

随着我国大量现代化大型建筑体系的出现,扣件式移动脚手架已不能适应建筑施工发展的需要,大力开发和推广应用新型脚手架成为当务之急,需要广大生产厂家注意和研制。实践证明,采用新型脚手架不仅施工安全可靠,装拆速度快,而且脚手架用钢量可减少33%,装拆工效提高2倍以上,施工成本可明显下降,施工现场文明、整洁 。所以在建筑施工中尽量使用新型的移动脚手架,保证施工的安全和可靠,不会或者减少施工中出现的倒塌事故。

With the emergence of a large number of modern large-scale building systems in China, fastener-type mobile scaffolding can no longer meet the needs of construction development. It is urgent to vigorously develop and promote the application of new scaffolding, which needs the attention and development of manufacturers. Practice has proved that the new scaffolding is not only safe and reliable in construction, but also fast in assembly and disassembly. The steel consumption of scaffolding can be reduced by 33%, the efficiency of assembly and disassembly can be increased by more than two times, the construction cost can be significantly reduced, and the construction site is civilized and neat. Therefore, we should try our best to use the new mobile scaffolding in the construction to ensure the safety and reliability of the construction, and not or reduce the collapse accidents in the construction.
